T 0 all whom it; may concern: I

Be it known that 1, MARK Moons, Jr, a citizen otthe United States, residing at Fairmont, in the county of Martin and State of Minnesota, have invented certain new and useful Improvements in'Tappet-Nrench Sets, of which thefollowing is a specification,

reference being had to the accompanying drawings. I t

The valve tappets on automobile motors are very important parts, and must be ad justed properly and kept in properadjush ment, necessitating the use ofa special thi For a long time automobile mechanics Whave been inlneed of' av set of tapp-et wrenches, which are capable of adjusting automobiles, hence the tappet and lock'nutson all makes of p the present qtappet Wrench set has beenfound to meet the need,

; as it-will cover the entire, ground... t i g One of the distinguishing features of a wrench of the present set is the 90 degree end, which isa distinct departure and one which is desirable by automobile repair men, in that it enablesthe user to reach tappets easily, and whi ch heretofore have been very difficult to'hold. 1 3 I I A purposeot the presentinvention is the provision of a tappet wrenchset comprising a plurality of wrenches preferably eight in number, though it is obvious that-the set may comprise anynumber of wrenches, as

circumstances warrant. i j

. It is a furtherpurposeuto construct each wrench from sheet a steel. preferably -10 gauge stock (of 9/64 ofan inch) ,though it is obviouswthat; any gauge material and thickness may be employed. 'The material may behardened to withstandthe rough usage, and furthermore it is the aimito construct one end of each wrench with jaws Whose sides: arefldisposed at an; angle of 22-1 degrees-with thecenteu line of the wrench: and the other end. has j aws' whose sides are formed at an angle of 90 degrees-with the center line oi thewrenchi' The angle ofthe 90 degree end may; be {varied 10 degrees either way. i Ithas been found that the novel feature of this wrench is the 90 degree end,asit will are formed at an angle other than 90*de gross- Thelreason forthis is that the 90 bilemay be engaged and adjusted withno,

into a close position. j .Also a wrench of the; present set is designed for adjusting lock nuts .on. brake bands on therear wheels oftautomobileseas there is a very small amount Ofi room or loss of time in tryingtoarrange the wrench space between the spokes of the wheels, in; i

which to use a-wrench otherwise constructed, thereforeit is the aim to provide. a wrench of the present character for ing lock nuts very easily. HIn certain automobiles the water pump is so placed that; it interfereswith the adjustment of the tappets, or it limits theiamount of room for a Wrench towork in, especially when adjusting the tappetson certain automobiles. The present form otwrench. of theset will engage thej tappets. (easily, and

of course'will decreasetheamountiof time used by the mechanics toifini'shthejobm i A. still turther and most important f purpose is the prov slon of a .tappetrwrenchset, wherein a pluralityi ofv tools or wrenchesareembodied, and wherein the tappet'engaging notch at one end of the tool body is of certain dimensions, while the other tap-.

pet engaging notch or recess or. opening is'of slightly increased d1m611SlODS,iWllll6 the ad'- reach,- a i jacent tool or wrench hasits end correspond-1 ing to the firstmentioned wrench end-pro= vlded wlth a notch or tappet engaging re cess of dimensions corresponding :to the di mensions of the notch rla'st -mentioned, so that the wrench set may be employed for ad.- justing the various tappets on-all makes of automobiles.

While the design and construction at present' illustrated and .set forth is deemedpreferable, it is'olovious that as a resultmfare duction of the. inventionto a-more'practical form for'commercial purposes; theiinvention maybe susceptible oi changes, and the right to. these changes is claimed, provided they are comprehended within the scope or what The invention comprises further features and combination of parts, as. will be hereinafter set forth, shown in the drawings and claimed. i

In the drawings Figure 1 is a view in perspective of a holderconstructed of any suitable material preferably canvas, duck or'any other material with spaces formed therein for the reception of a tappet wrench set.

Figure 2 is a plan View of a wrench with a 1/2 inch opening at one end and a 5/8- inch opening at the other end.

Figure 3 is a plan View of a tappet wrench with a 9/16 and: a 1/2 inch opening at its opposite ends, the former being on a 22. degreev end opposite to the end of the first wrench.

Figure 4 is a plan View of a tappet wrench with openings at itsopposite ends, one DIBELS- uring 11/16 inch on the 22 degree end, the other measuring 9/16 of an inch on the 9Ov degree end.

Figure 6 is a plan View of a tappet wrench IWith a 3/4of an inch opening on.

the 22 degree end and a 7/8 opening on the 90 degree end.

Figure 7 is a" planview of a tappet wrench provided with openings of different sizes,

one at the 22?; degree end measuring 13/16 of an inch, the other measuring one inch.

' Figure 8 is a planview of a tappet wrench with openings respectively of its opposite ends, one onthe 22% degree. end measuring 7/8 of an inch, the other ona 90 degree end measuring 3/45 inch.

Figure 9 is a. plan view of a tappet wrench having-a: one. inch opening on the 221} degree duck, said holder having a plurality of spaces. or compartments for the reception of the wrenches, there being. a cover or closure 2.

.Each wrench, thoughit may be made of any material. preferably metal ofany thickness,it is-designed to be made of steel, from 10-gauge stock, preferably 9/64 of an inch in thickness, and is hardened to. withstand rough. usage. V 1

Theopposite ends of each wrench body 4 are provided with enlargements 5 and 6.

The enlargemento is provided with wrench jaws 7 causingi-to'be formed anopening or recess 8 for engagementwith various tappets or locknuts on automobiles. The opposite edges of the: jaws 7, though they maybe disposed at any angle, are preferably disposed on an angle of- 22% degrees. The enlargement 6 of the other end is provided with jaws 9, which are spaced) in parallelism, causing tobe formed a recess or opening 10. The opposite edges of these jaws 9 are preferably disposed on an angle of 90- degrees relatively to the shank of the tool or wrench,

enabling the jaws to: readily reach tappets will be noted that these openings or recesses of the various wrenches are of different dimensions. For instance the opening or recess 8 may be of one-half inch measurement from the points indicated at a, while the recess or opening 10 may be of a measurement of 5/8 of an inch, while the opening" of an inch, and the opening at the opposite end of the adjacent wrench preferably'1 1/16 'of an inch, and so on 3/4 of an inch,13/l6 .ings of the same. dimensions, and furthermorev it will be found that the half inchooenin s are dis oosed on a 22% de ree an le r 2- Z b t) end, while the opening of9/16 is'disposed.

on a 90 degree angle end, while the 5/8 inch openings maybe found on the 22-} degree angle end of the second wrench, and the end of the" second" wrench and Vice versa. In other words the different openings may be varied, and furthermore no two openings are the same onany one wrench.

The invention having been set forth, what 7 is claimed. as being useful is As a new article of manufacture, a tappet wrench set COIHPI'lSlIlg a I plurality of wrenches, each having jaws at one end dis posed substantially at an. angle of ninety degrees, and jaws at. its opposite end at an angle of substantially twenty-two and a half degrees, the openings. boundedby both. de'-' gree jaws gradually increasing in. size 11/16inchopenings on the 90 degree angle throughout the set, the: open-ings between the ninety degree-jaws" being substantially the same asthose, whichlare between the twentytwo and a half degree jaws but advanced in location on a wrench, ahead throughout the successive wrenches of the. set, whereby no two openings .are the same on, any one wrench, thereby making it possible to adjust the tappets and lock nutsof the same'si'ze.
